STE M-WINDIIIG WAT OH.

To all whom it may concern:

Be it known that I, IIENRY W. MATALENE, a citizen of the United States, and. a resident of Boston, in the county of Suii'olk and State of Massachusetts, have invented certain new and useful Improvements in Stem-Fdinding Watches, of whichthe following is a specifica tion.

This invention relates more particularly to watches which are intended to be suspended from a neck chain or chatelaine pin secured to the person of the wearer and are made in i accordance, broadly speaking, with the invention set forth in a prior application for United States Letters Patent iiled by me on June 25, 1908, Serial No. e'40,217, which invention is characterized by the omission from the watch case of the usual pendant, crown and bow and by the suspension of the watch directly from the upper end of the winding stem in such manner that the only parts which project and are visible above the watch case, when the watch is suspended, are the outer or exposed portions of the suspending means attached to the winding stem, so that the back side of the watch presents the same external appearance as a locket. In said prior application I have shown and described certain constructions, applicable to stem winding and setting watches, which prevent outward movement of the winding stem when the watch case is closed but permit such outward movement when the Watch case is open, so that in setting the watch it is necessary to open the case in order that the winding stem may be moved longitudinally into setting position, and my present invention is particularly in tended to provide a stem winding and setting watch having the general characteristics above referred to but so constructed that the winding stem may be moved into and out of setting position without opening the watch case, to which end I provide a locking device which is mounted on the case of the watch and normally secures the winding stem against longitudinal movement, but which may be operated from the exterior of the watch case to release the winding stem and permit its movement into setting position whether the case of the watch is open or closed.

I l g i Specification of Letters Patent.

In the accompanying drawing: Figure 1 is I a face view, partly broken away, of a watch f constructed in accordance with my present invention; and Fig. 2 is a detail sectional Patented April 20, 1909. Serial No. 462,416.

view, the plane of section being indicated by the line r-rr in Fig. 1.

The watch illustrated in the drawing coniprises a center 2, a bezel 3, a cap 1, a back 5, and a crystal 6, which parts may be of any usual construction except in so far as the center and bezel may have to be modified as hereinafter described.

The upper portion of the winding stem is indicated at 7, and to the outer end of this stem is secured a winding cylinder or terminal 8, which is journaled in the peripheral portion of the center 2 and is provided with suspending means such as an eye 9 and a link 10 carried thereby. The winding stem 7 and cylinder 8 form, in eiiect, a single piece, and said cylinder 8 terminates at the rim of the watch case, so that the only parts which project beyond the watch case and are visible from the exterior of the watch are the suspending means above referred to. Near its upper end the winding stem 7 is reduced in diameter, as at 11, so that an annular groove or recess is provided between the shoulder thereby formed on the winding stem and the under side of the winding cylinder 8, and a locking plate 12 is mounted to slide transversely in the center 2 and is provided with a key hole slot of which the larger portion 13 is of suificient diameter to permit the winding stem to pass through it, while its smaller por tion 14 is of such size as to fit closely around the reduced end portion 11 of the winding stem. The side edge portions of said plate 12 are guided in suitable slide ways which may conveniently be provided by ledges 15 formed in the center 2 and a bottom plate 16 which is perforated to receive the winding stem and is secured to the center 2 beneath the plate 12, as shown in Fig. 1. Said locking plate 12 is normally held in the position shown in Fig. 2 by means of a spring 17 secured at one end to the center 2, in which position the portion 1 1 of its key hole slot embraces the reduced portion 11 of the wind ing stem, so that the portions of said locking plate which are adjacent to said portion 14 of the slot overlap the shoulder on the wind ing stem and thus prevent any outward movement of said stem.

The locking plate 12 is provided with an operating stem 18 which projects outward through the center 2 and the bezel 3 and terminates in a cup-shaped depression 19 formed in a slightly raised or thickened portion 20 formed on the rim of the bezel, so

that said operating stem 18 may be conveniently pushed inward to move the portion 14 of the slot in the locking plate 12 away from the portion 11 of the winding stem, and to bring the larger portion 13 of said slot into a position concentric-with the winding stem. Said locking plate 12 will be arrested in the position last referred to by engaging the side wall of the center 2, and when the parts are in this position the winding stem 7 can be pulled outward into setting position, and pushed inward into winding position after the watch has been set. As soon as said winding stem has been pushed inward into winding position the spring 17 will throw the opened, and it is to be understood that the details of construction of this locking device may be modified in various respects without departing from my invention.

I claim as my invention:

1. A stem winding and setting watch comprising a winding stem terminating at its outer end within the periphery of the watch case and having suspending means secured thereto, and a locking device mounted on the watch case and movable from the exterior thereof into and out of engagement with said winding stem to prevent and permit longitudinal movements thereof.

2. A stem winding and setting watch com prising a winding stem having a recess near its outer end, suspending means secured to said winding stem, and a locking plate mounted in the watch case and arranged to slide into and out of said recess, said locking plate being provided with a slot through which the winding stem is adapted to pass, and with an operating projection extending outward through the rim portion of the watch case and accessible for operation from the exterior thereof.

3. A stem winding and setting watch comprising a winding stem having a reduced por tion near its outer end, suspending means secured to said winding stem, a locking plate mounted to slide in the watch case, transversely to the stem, and provided with a key hole slot through the larger portion of which the winding stem is adapted to pass, said locking plate having an operating projection extending outward through the rim portion of the watch case and accessible for operation from the exterior thereof, and a spring arranged to force said locking plate into locking position.

In testimony whereof, I have hereunto subscribed my name this 10th day of November, 1908.
